I doubt I have a slow puncture on every single tyre. They're not even that old. The tread is fine on them all. The car passed a full MOT and Service back in July.

Any ideas? :confused:

When you live with your parents Dad pumps them up every sunday morning while you fester in your pit,once you leave home you suddenly realise they lose pressure and start looking for a high tech reason for it happening[any thing rather than get the foot pump out ];)

Another option is to fill with nitrogen, the molecules are thicker the O2 ones, leak less

People at work fill their tyres with nitrogen.

The joys of filling plane tyres.

This always makes me smile, you know "air" is 78% Nitrogen anyway ?

So if you only fill them 3/4 full job sorted ;)

In the old days I used to invest in an inner tube for troublesome wheels.
